PEG-7

INCI PEG-7

Polyethylene Glycol / Solvent-Humectant Hydration & Barrier

What it is & what it does

PEG-7 is a low-molecular polyethylene glycol used mainly as a solvent and humectant.
It helps dissolve ingredients and improves moisture retention and spread. Its direct skin benefit is modest hydration rather than a treatment effect.

Usage & cautions

Information approach Consumer-friendly summaries are informed by established cosmetic ingredient references such as INCIDecoder and Paula’s Choice Ingredient Dictionary, while avoiding turning ingredient-level evidence into medical claims about the finished product.
